To develop a non‐precious highly efficient cocatalyst to replace Pt on graphitic carbon nitride (g‐C3N4) for solar H2 production is great significant, but still remains a huge challenge. The emerging single‐atom catalyst presents a promising strategy for developing highly efficient non‐precious cocatalyst owing to its unique adjustability of local coordination environment and electronic structure...
Bismuth oxyselenide (Bi2O2Se) has emerged as a promising candidate for electronic and optoelectronic applications due to its outstanding electron mobility and ambient stability. However, high dark current and relatively slow photoresponse that originate from high charge carrier concentration as well as bolometric effect in Bi2O2Se inhibit further improvement of Bi2O2Se based photodetectors. Here,...
A parallel double helix wire‐shaped supercapacitor protocol has been developed by H. Li, T. Zhai and co‐workers, presented on page 1024. Two symmetric titanium@MnO2 fiber electrodes are wound on a flexible nylon fiber by a simple and reliable process. Due to rational structure design, the devices demonstrate excellent mechanical and electrochemical stability under both static and dynamic deformations...
Wire‐shaped flexible supercapacitors (SCs) have aroused much attention due to their small size, light weight, high flexibility, and deformability. However, the previously reported wire‐shaped SCs usually involve complex assembly processes, encounter potential structural instabilities, and the influence of dynamic bending on the electrochemical stability of wire‐shaped SCs is also not clear. Here,...
